AUSTIN D. BRIXEY, OF NfiW YORK, N. Y., ASSIGNOR T0 ORDINATOR COMPANY INC v A CORPORATION OF NEW YORK. I,

MULTIPLE SHADE-ROLLER.

To all whom it may concern.

Be it known that I, AUsrIN D. BRIXEY, a citizen of the United States, residing at city, county, and State of New York, have invented new and useful Improvements in Multiple Shade-Rollers, of which the foldow structures which have come largely into use in connection with concrete and other buildings, namely that type where the glass panes are secured in a metal frame including fenestra windows, which has the material of the wall cast about it or is otherwise immovably secured therein. With such structures the opening of a fenestra window would interfere with the operation of the shade for all partsof the window if one shade extended across the entire window. Independence of control of the covering of different parts of the window may be effected so that the opening of a fenestra window will not interfere with the whole window area, by dividing the shade into several. In the type of window referred to, however, there is scant means for securing shade supporting brackets, except, at the marginal frame of the entire window, and furthermore the multiplicity of brackets required for supporting a number of shade rollers,-

would be unsightly.

It is the main object of the present invention to provide multiple shade rollers whereby division of control of the window areas will be secured, but which shall ordinarily require support only at the sides of the entire window, which shall present a neat appearance andbe simple in construction. This is accomplished by mounting a plurality of independently operable shade rollers of the desired dimensions upon a rod which may extend from one side of the window to the other.

A further object of the invention is to provide improved structures of shade rollers.

Qtherand ancillary objects of the inven: tion will appear hereinafter.

Specification of Letters Patent. Patent d pl 10 1921 Application filed August 15. 1917. Serial No. 186,287.

Figure 1 is a front elevation of a window to which the improved shade structure is applied;

Fig. 2 is a view on an enlarged scale partly in section and partly in elevation of the shade roller structure of Fig. 1, the 1s itructure being partly brokenaway in this Fig. 3 is a section on the line 3-3 of Fig. 2, and Fig. 4 Fig. 2.

Referring to the drawings within the frame 1 is mounted a window comprising fenestra windows 2 and 8. This is a type of wlndow extensively made use of in concrete buildings, the pane holding frame being made of metal and immovably mounted in the concrete wall, ventilation being controlled by the opening and closing of the fenestra windows. e

The rod 4 extends continuously across the window and is supported in brackets 5 and 6 secured to the frame and of a structure as is well known in connection with the support of Hartshorn shade rollers. Thus the bracket 5 has a squared recess for receiving a squared projection from the rod 4 while the bracket 6 has a round aperture for receiving a round pintle at the other end of the rod.

The rod 4 is shown as hollow, that is as a tube in the ends of which are secured the plugs 7 and 8. The tube forms a stiffer structure than a solid rod so that the tendis a section on the line 44 of ency to sag, in long lengths, is more effec-' tively opposed. The plug 7 carries the squared projection 9 for entering the squared recess of the bracket 5 to prevent turning of the rod 4, while the plug 8 has the round projection 10 to enter the aperture in the bracket 6. I

Upon the rod 4 are rotably mounted the separate rollers carrying shades 11, 12, 13, 14 and 15 which are independently operable so that the several shades may be raised and lowered independently.

Each of the rollers comprises ashell or tube16 on which the shade is secured and rolled after the usual manner of shade rollers. The shell is fixed to disks 17 and 18 rotatably mounted on the rod 4, by

screws 19 and 20. The disks nearest the ends of the rod have hubs 21 and 22 adapted to bear against flanges 23 and 24.- on the plugs 7 and 8 to properly space the end rollers from the ends of the rod. Adjacent ends of the rollers intermediate theends space as 27 is formed between their ends. A s rinrr 28 tends to turn the disk 18 to- P as gether with the disk 17 and the shell 16 about the rod l in a direction to roll up the shade. As will be seen, this spring is coiled about the rod and has one end 29 secured to the rod by passing it through holes 30 and 31 therein, and clenching the end of it. The other end of the spring is secured to the disk 18 by passing it through a hole 32 in the disk and turning up the end 33. The roller is held against turning on the rod 4 by means of dogs at and 35 pivoted on the disk 17 and adapted to engage in recesses 36 and 37 in the rod a. The apertures are of such'size with relation to the dogs, that when the roller turns slowly, the upper dog will drop into an aperture and arrest its rotation; while on the other hand the dogs are made of such weight that when the roller rotates at a comparatively high rate of speed, their inertia and centrifugal force prevent them from dropping into the aperture and consequently the rotation of the roller is not arrested. The object of having apertures 36 and 37 on op posite sides of the rod 4, is to enable it to be installed in either of two positions 180 apart, butthe squared end 9 and its cooperating recess in the bracket, will not permit it to be installed in any intermediate position, it being understood that the squared end is of greater dimension in one direction than in the other, as is customary with the squared pintles of shade rollers.

It will be observed that the shades may be made ofdiflt'erent desired widths, so that various portions of the window maybe in dependentlycovered 0r uncovered; also it will be seen that where the opening of the fenestra windows interferes with the drawing down of the shade over them, this does not prevent the operation of the shades covering other portions of the window. If the window were covered by a single shade ex tending across it, the opening of a fencstra window would interfere with the adjustment of the shade over the entire window.

It willfurther be observed that the structure of roller provided is very easy of adjustment and assembly. The tube constihating the rod 1 may be cut to any length desired and the necessary bracket attaching means secured to its ends. The rollers can then be mounted upon the rod by sliding a disk as 17 thereon, this carrying the stop dogs, as described. The spring and other disk may then be threaded on the rod and finally the shell 16 may be threaded over the disks and secured thereto by the screws as 19 and 20. A similar operation serves to assemble the next roller and so on throughout the length of the structure.

, While theinvention has been illustrated in what is considered its best embodiment, it may be embodied in other structures without departing from its spirit and is not therefore limited to the structure shown in the drawings.
